Airdrop Alerts does some sanity checking on the drops they feature, I would just sign up for them all.
Make sure you don't use your main email account to sign up (get a hotmail account specifically for these) as you will get a load of crap sent to it. I would also fund the Eth account you are using with about $10 (you'll need some gas money for selling tokens).
do you recommend ones to do? i checked a few out it seem they just want a little info for some free coins
